Fluuval or Sump

[jimmyg]

I currently have a Fluuval 305 on my 3ft grow out Tank and have had the Ammonia sky rocket twice. I have ran into another problem I have another 2 lots of smaller babaies coming up, so I ma looking at sumping my Grow out Tanks.

Is it a good Idea or not?

I have heard and read a bit about this Seachem Matrix and it says it good for lower Ammonia and I add it to my sump.

My newest batch is about 2 weeks old and there is about 180+ so i will need lots of filtration for these, I am totally new to this as I am so use to breeding Bristlenose.

Thanks
Jimmy

I use Huey Hung type sponge filters, and thats all in grow out tanks, no need for anything fancy imo
